Heh, good eye. Ultimately, I'm a pragmatist, and there isn't a blogging platform as flexible and as powerful as WordPress built in Rails. I like to think it is my pragmatic approach to learning Rails that separates my workshop from other ("Kitchen sink included!") training options.
But to keep it a part of my normal Rails workflow, I'm running WP on Heroku (http://decielo.com/articles/350/wordpress-on-heroku-up-and-r...), and using it with Pow locally. :]
That config stood up to HN traffic quite well on the one free dyno from Heroku.
